Linear Technology LTC2320CUKG-14#PBF

Description
The LTC2320-14 is an octal, 14-bit sign, 1.5Msps/Ch simultaneous sampling ADC with differential inputs and a wide input common mode range. It operates from a single 3.3V or 5V supply and has an 8Vp.p differential input range. The LTC2320-14 achieves ±1LSB INL typical, no missing codes at 14 bits, and 81dB SNR. It has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2320-14 also has a high-speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 1.5Msps per channel throughput with no latency makes the LTC2320-14 ideally suited for a wide variety of high-speed applications. It dissipates only 20mW per channel and offers nap and sleep modes to reduce the power consumption to 26pW for further power savings during inactive periods.
